Report 69291: Possible "Ohio howls" south of Shingletown (midway between Redding and Lassen)

While living with my parents at Manton, CA. in 1987-1989, we began hearing strange howls intermittently from about 9 PM to midnight 2-3 times a week. My father said their crazy neighbor must have gotten hold of a WW 2 air raid siren. I think he said that so as not to scare kids. It was definitely NOT the local volunteer fire dept. siren.  Not until several years later did we happen to hear a recording of the "Ohio howl"-- exactly the same sound. It made the hair on the back of my neck stand on end to recognize it. My husband and grown children also recognized it and said "That's the sound we used to hear at Manton!" Looking back, I realize the sound came from the cleared swath going up the hill along the penstock or the powerlines. At the time, not many people lived in the area, lots of wildlife that just came into yards, game, cougars, water.
